Abstract
This invention relates to the process of using a catalyst for the photo-catalytic degradation of methyl tertiary butyl ether (MTBE) in water. A Pd/Ce2O3—ZnO photo-catalyst is formed to react with MTBE dissolved in water sample and UV irradiated to reduce the MTBE concentration in the water sample. A 95-97% degradation of MTBE is observed using this process.
Claims3
A process, comprising:
- fitting a cooling jacket;
- adding a Pd/Ce2O3—ZnO photo-catalyst into deionized water containing MTBE and forming a solution;
- loading the solution onto a photochemical reactor and stirring continuously;
- collecting a sample from de-ionized water containing MTBE and designating as an initial concentration of MTBE (Co);
- saturating the sample by passing an oxygen gas using an inlet tube through the sample;
- exposing the sample from the saturating step to UV light;
- collecting the sample after exposing to UV light at a regular interval of time and estimating a reduction of an amount of MTBE in the sample using a gas chromatography.
